The kinematic equation v² = u² + 2as explains the change in velocity (v) of an object under constant acceleration (a). The equation demonstrates that the final velocity squared is equal to the sum of the initial velocity squared (u²) and twice the product of acceleration (a) and displacement (s). It elucidates that an object’s final velocity is influenced by its initial velocity, the rate of acceleration, and the distance it travels. This equation quantifies the relationship between these variables, providing a concise expression for understanding and predicting changes in velocity during uniformly accelerated motion.
If the acceleration of an object is zero, its velocity remains constant.

If the acceleration of an object is zero, its velocity remains constant. According to Newton’s first law of motion, an object at rest stays at rest, and an object in motion continues at a constant velocity unless acted upon by a net external force. When acceleration is zero, there is no net force acting on the object, so it maintains its current state of motion. If the object is at rest, it remains at rest; if it is in motion, it continues moving at a constant speed in a straight line. In summary, zero acceleration implies a lack of change in velocity.
The kinematic equation v² = u² + 2as is not directly applicable to objects moving with variable acceleration because it assumes a constant acceleration (a).

The kinematic equation v² = u² + 2as is not directly applicable to objects moving with variable acceleration because it assumes a constant acceleration (a). For variable acceleration scenarios, calculus-based equations, such as those derived from the equations of motion or integrating acceleration functions, are more suitable. These equations can provide insights into the changing velocity and position of an object under varying acceleration conditions. Therefore, while v² = u² + 2as is powerful for constant acceleration situations, it has limitations in accurately describing the behavior of objects with acceleration that changes over time.

Potential energy is intimately related to the concept of work. Work (W) is done when a force is applied to an object, causing it to move over a distance. When a force acts against gravity, for instance, lifting an object against Earth’s gravitational pull, work is done, and the potential energy of the object increases. The work done (W) is equal to the change in potential energy (ΔPE). This relationship is expressed by the formula W = ΔPE. Thus, potential energy is a measure of the capacity to do work, and work done can lead to a change in an object’s potential energy.
